It has been cited often that on Summoners' Rift ranked solo queue, blue side wins around 55% of the time. The effect of the "blue side advantage" is so great that it is often said that Riot puts slightly higher elo teams on the purple side in an attempt to balance out the map advantage by simply spawning on the blue side.
I have been interested in this in a while, but as far as Summoners' Rift is concerned, there are several factors one needs to consider:
1. Spawning position of jungle monsters.
2. Dragon/Baron lay out.
3. Pick order (in ranked).
4. Camera angle.
With the introduction of One For All Mirror Mode on the ARAM map, it creates an unique situation which:
1. No jungle.
2. No Dragon/Baron.
3. It's the same champion times 10.
But the camera angle remains. So on this map we actually remove a lot of the other factors which may make the blue side stronger. With this in mind, I quickly found ~3500 games played on this new game mode during the last 4 hours or so. I got the following:
Blue side won: 1946 games
Blue side lost: 1505 games
So overall, blue side wins 56.4% on One For All Mirror Mode. This estimate is accurate within plus or minus 1.6%, 19 times out of 20. This is very similar to the blue side win rate on ARAM maps in general, which is around 56%.
In comparison, on Twisted Treeline where the map is totally symmetric and camera angel is not an issue, the blue side (left side) wins exactly 50% of the time.
So, it does look to me that there is an effect from camera angle that makes the blue side stronger on Summoners' Rift and on ARAM map. I wonder what the consequence is, especially on the competitive scene. It almost feels to me that playing on the blue side is sort of like playing as white on chess - while the advantage is not as big as white side on chess, the advantage is certainly there and it's real.

Early game champion / late game champion analysis
I always hear about players saying "Champion X has great late game", or "Champion Y falls off really hard". But I wonder how much of the players' perception can be proven using actual game data?
I thought of one idea. Suppose we think, say, Vayne is very strong late game and very weak early game. Then we should expect Vayne to lose a lot more often if the game is short and win a lot more if the game is long. To do this, I drew 860k ranked solo queue games played in Patch 4.6 and computed each champion's win rate segmented by game length. The result is summarized below.
For example, we see that Vayne wins around 45.73% of the time overall. If the game is less than 25 minutes long, however, she only wins 41.31% of the time. On the other hand, for games over 50 minutes, Vayne wins 52.65% of the time. That's a huge difference!
Some of my personal analysis are below this table.
Here's what I can see:
- Karthus, Twitch, Vayne, Veigar are late game monsters.
- Kennen, Shaco, and Alistar are surprisingly strong late game.
- Anivia and Ziggs seem to have WEAK late game, which is very interesting.
- Jinx's late game does not seem to be that strong. She seems to be more of an early game champion.
- If you look at Tristana, it seems that she wins a lot more in very short and very long games, while lackluster in a medium length game.

How to raise division/MMR without playing better
- Allow your teammates to carry you. You are playing to win, not to be a big shot who carries every game. In fact, you probably cannot carry every game unless you are smurfing. If you are 1-9 but your teammates are all 9-1, don't bitch about your score - just stay safe, relax, listen to calls, and let your teammates win the game for you.
- When your teammates are throwing, remember your opponents can be just as likely to counterthrow. The matchmaking algorithm dictates that your teammates and your opponents have similar skill level. If your teammate is throwing, your opponents can throw too. Until the nexus falls you can always seize the opportunity to win.
- Don't question bad plays. Remember your teammates also want to win - they are not intentionally feeding your opponents as an attempt to make your life harder. When they make bad plays, they already feel bad themselves, so there is no need for you to spray salt onto their wounds. I recommend you say absolutely nothing about it and keep your mouth shut. You are here to win the game, not to belittle some random person on the internet who made an honest mistake.

| Thresh | 36.243% | 5.305% |
| Yasuo | 33.686% | 6.165% |
What I do NOT find surprising:
- Nidalee, Soraka, Sona, Jayce, Helicopter-Pony win like crazy.
- Yasuo, Rumble, Cassiopeia suck, since they gain very little from the 80% CDR.
- Lux is mediocre. Her R spam is decent, but no match for the sustain from some of the better champions.
What I DO find surprising:
- Galio wins like crazy. This is probably due to his W spam and his MR scaling against a meta that is almost all magic damage poke.
- Nami wins like crazy. Not quite sure what happened here, especially if you consider the fact that her E is not too useful and does not scale well with CDR. Perhaps due to a combination of sustain from her W and her damage/CC from Q + R.
- LeBlanc is played often, but she isn't too good. Despite what Riot said during the TSM vs C9 match, you cannot perm root someone with her E spam.
Note:
- Unfortuantely, ban rates are not available. I do suspect Nidalee and Sona are actually banned quite a bit. When Nidalee gets picked, for example, around 1/3 of the games will have Nidalees on both sides.
- Win rates are calculated only in games which the champion in question is played on one side. This makes sure an overwhelmingly popular champion does not have close to 50% win rate.
